People are being lured (引诱) onto Facebook with the promise of a fun and free service without realizing they're paying for it by giving up large amounts of personal information. Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages.
Most Facebook users don't realize this is happening. Even if they know what the company is up to, they still have no idea what they're paying for Facebook, because people don't really know what their personal details are worth.
The biggest problem, however, is that the company keeps changing the rules. Early on, you could keep everything private. That was the great thing about Facebook—you could create your own little private network. Last year, the company changed its privacy rules so that many things—your city, your photo, your friends' names—were set, by default (默认) , to be shared with everyone on the Internet.
According to Facebook's vice-president Elliot Schrage, the company is simply making changes to improve its service, and if people don't share information, they have a "less satisfying experience."
Some critics think this is more about Facebook looking to make more money. Its original business model, which involved selling ads and putting them at the side of the page, totally failed. Who wants to look at ads when they're online connecting with their friends?
The privacy issue has already landed Facebook in hot water in Washington. In April, Senator (议员) Charles Schumer called on Facebook to change its privacy policy. He also urged the Federal Trade Commission to set guidelines for social-networking sites. "I think the senators rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them," Schrage admits.
I suspect that whatever Facebook has done so far to invade our privacy, it's only the beginning, which is why I'm considering deactivating (撤销) my account. Facebook is a handy site, but I'm upset by the idea that my information is in the hands of people I don't know. That is too high a price to pay.
This document sets out the display standards for Glasgow Museums. This guide will help exhibition planners provide access to exhibitions in our museums. Glasgow Museums' aim is to improve access to collections by having as many items as possible on display and without physical barriers. We also try out best to protect these objects without limiting access to them.
Object Placement
·Don't place objects in such a way that they could present a danger to visitors.
·All object displays, cased or otherwise, must be viewable by all, including people who are small in figure or in wheelchairs.
Open Display
·All objects on open display must be secure from theft and damage.
·All objects identified for potential open display must be viewed and agreed on an object-to-object basis by the Security Manager of the museum.
Recommendations | Distance |
Recommended distance to place objects out of “casual arm's length”(taken from the edge of the object to the edge of any proposed form of barrier) | 700mm |
*In some cases, 600mm may be acceptable, provided the plinth height is above 350mm.
Cased Objects
·All cased displays should fall within the general optimum(最优的)viewing band of 750-2000mm. Ensure everything is visually accessible from a wheelchair.
·Position small objects or those with fine detail in the front part of a case, with larger items behind.
·Position small items or those with fine detail no higher than 1015mm from floor level. Objects placed above this height are only seen from below by people in wheelchairs or people who are small in figure.
